Customer Reviews (4.8 / 5 · 5 reviews)

Timothy ★★★★★

The 80 durometer feels perfect for my hydraulic press—snug fit with no squishing. I’ve used these at around 250°F without any swelling or cracking.

Jason L. ★★★★★

Had a stubborn refrigerant leak on a compressor fitting, and these 441-sized rings sealed it up perfectly on the first try. The 80 durometer material feels noticeably sturdier than the standard ones I'd been using, and the -40°F rating gives me peace of mind for winter operation.

William ★★★★★

Put these on a hydraulic line that sees a lot of heat cycles, and they’re holding up perfectly so far—no cracking or hardening. The 80 durometer feels stiffer than standard o-rings, which is exactly what I needed for that high-pressure seal.
